Even with a loss tonight, the series is tied and the Jazz still have home court advantage. So far, the Clippers haven't shown they are able to beat the Jazz in SLC. Plus, with each passing day the Jazz get a bit healthier.
Frankly, this is a do or die game for the Clippers. If they lose tonight, the series is over. If the Clippers win tonight, it will be a dogfight the rest of the way, but I still think the Jazz prevail, likely in 7.
